Why spend your summer vacation on subways and buses when you could be out exploring places on two wheels?

Thanks to an explosion in bike-share systems and a general appreciation for bike culture, making cycling a central part of your travels is becoming easier and easier. You don’t have to throw down, pack your bicycle and head off on a full cycle tour to get the pleasure of seeing a place on two wheels; there are plenty of cities around the world that are bike-friendly and perfect for anyone who enjoys the thrills of riding in a new place.

Here are the ten best places to explore by bike.1. Amsterdam
There’s no denying that if you’re a bike lover, Amsterdam should be at the top of your list. Here people are practically born on bicycles, and if you want to experience the city like a real local, there’s no better way. Start off in the Jordaan district, rent a bike at the friendly Bike City and get ready to master the dance that is cycling in the Netherlands.

3. ​Portland, Oregon
Beer, baristas and bikes; it’s the Portland trifecta. You can get all three at Velocult, the city’s hub for bike related events and general fun. If you’re downtown you should be sure to hit up the Courrier Coffee Bar, opened by one of the city’s favorite pedal-delivered craft roasting companies. Add Trailhead to the list as well, another bike-powered artisan roaster. And when you’ve had enough pedal-powered caffeine for the day, take your bike, roll over to the bike-centric bar Apex and drink one of their 50 beers on tap.

4. Paris
Ok, so Paris might not be the first place that comes to mind on the list of bike-friendly places – you do have to do a lot of scooter and pedestrian dodging – but thanks to the successful Velib bike-share system, cycling is a big part of Parisian culture. The key in Paris is to identify that bike paths; you’ll find separated lanes around the city that make two-wheeled Paris a true delight.

5. San Francisco
Don’t let the hills scare you off. Through the late spring and early fall you can take advantage of Sunday Streets, a collection of events that closes off streets to cars in different neighborhoods around the city, and in Golden Gate Park there are car-free Sundays and Saturdays. For a longer adventure, make your way to Marin County.

6. Berlin
Berlin is in the top 10 of bike blog Copenhagenize’s bicycle-friendly cities and with good reason. Around 13% of the population ride their bike on a daily basis, and in some neighborhoods it’s as high as 25%. There’s the 1st Bicycle Gallery which is all about showcasing gorgeous bicycles . There’s an online route planner you can use to facilitate your ride, and if you want a different look at one of the city’s most iconic landmarks, cycle the Berlin Wall Trail, tracing the former wall.

8. Barcelona
Beach and bikes; it’s no surprise that Barcelona is popular with budget-savvy travelers looking for a little warm weather and outdoor strolls. There are over 100 stations for the city’s Bicing program, and a variety of rental and tour options. Top that ride off with some tapas and you have the perfect day.

9. Montreal
Montreal is the place to be if you’re a cycle lover. There are trails, separated lanes and designated biking streets, easily navigable on PedalMontreal. The city is also the gateway to Quebec’s Route Verte, boasting over 5,000 kilometers of bikeways all over the region along with bike-friendly accomodations. You may need a few weeks.

10. Bogotá
Bogotá’s CicloRuta s one of the most extensive in the world. Given that a very small percentage of the local population has access to cars, bicycles make economic sense. If your destination is too far to ride to, the network of bike lanes connects well with the local transportation system, complete with bike parking at several designated stops. As the city’s ex mayor Enrique Peñalosa said, “I think the future of the world has to do with bicycles.”

Rio de Janeiro boasts some of the beaches you’d spy on calendars, postcards and the odd screensaver in your dentist’s office cubicle farm. So when we passed through on a whirlwind trip to Brazil, I took the advice of our friend Kent Wein to jump off a mountain to get a better look at things, as they say.

Paragliding – it’s a growing sport in this South American country, and it’s easy to find a good safe pilot who can take you up on a beautiful tandem jump over the city. Take a cab down to the beach at the foot of Pedra Bonita to get started. At this landing zone you can find the right group and get your adventure started.

Today is March 14, also known as Pi Day (in case it’s been awhile since you took math, pi is the ratio of a circle’s circumference to its diameter, 3.14), a day to celebrate mathematics, or just eat some pie. If you are in Cambridge, Massachusetts, today and can remember a good portion of the many digits of pi, you might get to eat some free pie. Today’s Photo of the Day by Flickr user autisticglobetrotting2010 is a bit math-inspired: the cross at the ceiling of Rio de Janeiro‘s San Sebastian Cathedral hints at a plus sign. The modernist cone-shaped church is highlighted by four enormous stained glass windows that form at the top with a cross. Designed to echo the Mayan pyramids, the distinctive structure is hard to miss in the Rio skyline.

Oi from Rio de Janeiro, where I’m traveling and soaking up some serious holiday sun. Staying at a guest house in bohemian Santa Teresa, I got to talking to artists and curators from all over the world the other night about cities. We talked about cities going through urban renewal and creative renaissance, such as here in Rio, Berlin, Havana, and even Detroit. The meaning of the phrase “ruin porn” made sense across multiple languages and cultures, and how popular that type of photography is with travelers. Today’s Photo of the Day shows some urban “decay” in Cuba‘s Havana, but I wouldn’t call it a ruin. It’s a more hopeful image; we can imagine that it’s not a decaying building, but a house in transition. The fraying image of the Cuban woman and the colored buildings are proof that someone tried to make it beautiful.

I love going through Vimeo slowly, looking for diamonds in the rough of time-lapse videos. I found one today. Created by Joe Simon, this time-lapse explores Rio de Janeiro. Featuring the simplistic beauty found in the subtle swaying of anchored boats, the coming and going of beach-goers, the overwhelmingly perfect sunshine and the gorgeous curves of the landscape, this video is worth the few minutes it takes to view it. So sit back, relax and enjoy Rio de Janeiro from afar.
